Ⅰ. Why Focus on Total Cost of Ownership (TCO)?
Traditional transformer selection often falls into the "low-price procurement trap"—saving 15%~30% upfront but incurring 3~5x hidden costs due to high energy consumption, frequent failures, and short lifespan. Our solution rebuilds value standards via dual engines: "Lowest TCO" + "Sustainability":

​Cost Type

​Traditional Transformer Pain Points

​Our Optimization Strategy

Procurement Cost

20% of TCO

Moderate increase in high-efficiency materials

Operating Electricity

>60% of TCO (over 30 years)

​↓30%~50% Losses​

Downtime Losses

​↑95% Material Recovery Rate

II. Core Solution: TCO & Sustainable Design Matrix

  1. Energy-Saving Core: Ultra-Efficiency Design
    Material Innovation:
    • Amorphous alloy core (↓65~75% no-load loss)—ideal for 24/7 operation.
    • Laser-scribed silicon steel (↓15% load loss)—optimized for high-load industrial scenarios.
      AI Electromagnetic Optimization: Custom winding structures via multi-physics simulation eliminate hot spots, achieving >99.7% efficiency.
      → ​Case Saving:​ 50MVA mining transformer saves >¥200,000/year (electricity: ¥0.1/kWh).
  2. Zero Unplanned Downtime: Reliability & Longevity
    Thermal Management Revolution:
    • Dynamic liquid cooling (↓15°C operating temp).
    • Class H insulation (180°C tolerance).
      Disaster-Resistant Design:
    • ↑50% short-circuit withstand (IEC 60076).
    • Seismic Level 9 (IEEE C57.140 compliant).
      → ​Lifespan Commitment:​ >35 years (industry avg.: 25 years).
  3. Maintenance Cost Disruptor: Smart & Maintenance-Free Design

III. TCO Decision Tool: Making Hidden Costs Transparent
Key Report Metrics:
• Payback Period: ​<3.5 years​ (high-load scenarios).
• 30-Year Net Present Value (NPV): ​↑$1.2-2.8 million.

IV. Implementation: End-to-End Value Delivery

  1. Audit:​ Collect load curves, environmental data, and electricity pricing.
  2. Custom Design:​ Material selection (amorphous alloy/silicon steel) + cooling (ONAN/ONAF/OFWF).
  3. Sustainability Certification:​ EPD + carbon footprint label.
  4. Smart O&M Package:​ 5-year cloud monitoring service included.
  5. EOL Circularity:​ 15% residual-value buyback (for remanufacturing).
